Python:将坐标从文本文件传递给海龟 [英] Python: Passing coordinates from text file to Turtle

问题描述

我有一个带有坐标的测试文件，我的目标是创建一个函数，该函数接受文本文件并将其转换为坐标以在海龟中绘制以绘制图像:

I have a test file that has coordinates on it my aim it to create a function that takes the text file and turns it into coordinates to plot in turtle to draw an image:

river, 5
500, 500
-500, 360
400, 500

shadow, 4
500, 300
5, 500
300, 400

到目前为止我有以下内容

so far I have the following

f =open("coordinates.txt", "r")
for line in f:
    line=line.split(",")
    data=[]
    if line:
        data.append([i.strip() for i in line])

运行后我得到以下内容:

After running I get the following:

    [['river', '5']]
    [['500', '500']]
    [['-500', 360]]
    [['400', '500']]
    [['']]
    [['shadow', '4']]
    [['500', '300']]
    [['5', '500']]
    [['300', '400']]
    [['']]

但是当我通过乌龟时它会坏掉并且不起作用.我的乌龟功能如下:

But when I pass it through turtle it breaks and does not work. My turtle function is as follows:

p=[]
letter=block[0]
for line in block[1:]:
          l.append(line)
k=p[0]
turtle.setpos(k[0],k[1])

推荐答案

这似乎是一个随机的代码集合，而不是一个程序.下面是我从数据和代码重建程序的意图.数据按如下方式读入列表:

This seems to be a random collection of code rather than a program. Below is my reconstruction of the intent of the program from the data and code. The data gets read into a list as follows:

[('river', '5'), (500, 500), (-500, 360), (400, 500), ('shadow', '4'), (500, 300), (5, 500), (300, 400)]

然后用乌龟画成线.

import turtle

turtle.setup(1000, 1000)

data = []

with open('coordinates.txt') as my_file:
    for line in my_file:
        line = line.rstrip()

        if line:
            x, y = line.split(', ', maxsplit=1)

            try:
                data.append((int(x), int(y)))
            except ValueError:
                data.append((x, y))

print(data)

turtle.penup()

for pair in data:
    if isinstance(pair[0], int):
        turtle.setpos(pair)
        turtle.pendown()
    else:
        print('Drawing {} ({})'.format(*pair))
        turtle.penup()

turtle.hideturtle()

turtle.done()

我不能说示例图很有趣:

I can't say the example drawing is at all interesting:
